CONDUIT CAP FOR ELECTRIC INSTALLATION.

Application filed November 1, 1919.

To alt 2071 0112 may concern:

Be it known that I, l rrnnnnn H. Vienna, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented a new and useful Improvement in Conduit Capsfor Electric Installation; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact de scription ofthe same, and which said drawings constitute part of this application,and represent, in

Fig. 1, a view partly in side elevation and partly in vertical sectionof a conduit-cap constructed in accordance with my invention, shown asapplied to a. shingled surface. Broken lines in this figure indicatethat the mounting-arm of the bracket may be turned downward instead ofupward if desired.

Fig. 3, a plan. view thereof showing its carrying-arm extended by brokenlines and reinforced by a brace also shown by broken lines.

My invention relates to an improved conduit-cap for electricinstallation, the object being to produce a conduit-cap of the typeadapted to be secured to and supported by a building, a pole or otherconvenient means of support extraneous to the conduit-pipe itself, andalso adapted to take the total strain of the scrvh're wires so as totvoid the necessity of any other support for them. The special object ofmy invention is to produce a simple and cheap conduit-cap of the typedescribed, adapted to be fitted for use in a variety of situationswithout any other change than varying the length of its mounting or itscarrying-arm or both.

lVith these ends in view my invention consists in a conduit-cap havingcertain details of construction and combinations of parts as will behereinafter described and pointed out in the claim.

In carrying out my invention, I employ an open ended angular strap-likebracket or frame comprising a vertical mounting or suspension-arm 2 anda horizontal carryingarm the said bracket being made by preference froma suitable length of heavy sheet Serial No. 334,992.

metal and the arms 2 and 3 being located at a right angle with respectto each other. The arm is perforated as at 4t for the re ccption of thebolt 5 by means of which the bracket is firmly secured to the wall of abuilding or to some other support extra i'ieous to the conduit-pipe 6.As shown, the said wall is indicated by shingles 7, the arm 2 being longenough to lap over two shinglesv The said arm 2 may obviously beincreased or decreased in length according to mounting requirementswithout in any other way changing the structure of the fixture as awhole or in detail.

The carrying-arm 3 of the bracket is formed well within its outer endwith a vertical, threaded opening 8 adapting it to be screwed upon thethreaded upper end of the conduit-pipe 6, but it is to be clearlyunderstood that the aid conduit-pipe is not relied upon to carry theweight of the conduit-cap and wires or cable nor to resist the strainsimposed upon the fixture by the same, such weight and strains beingdevolved upon the suspension or mounting-arm 2 aforesaid. Upon the upperface of the outer end of the arm 3, I mount the insulating cleats orblocks 9 and 10 which are secured together and to the arm 3 by means ofscrews 11 passing down through them and into threaded holes 12 in theouter end of the arm. These blocks or cleats 10 and 11 are also clampedupon the cable or the wires by means of the screws 11. They are enclosedand protected by means of a sheet metal hood 13 which also covers theopening 8 in the arm 3 and hence excludes water from the pipe 6, thesaid hood being secured in place, as shown, by screws 14 passing throughits lower outer corners and entering the edges of the arm 3 near theouter end thereof.

If desired, the arm 3 may be extended to any length without otherwisechanging the conduit-cap, for the purpose of moving the opening 8 andhence the pipe 6 away from the wall to which the conduit-cap is applied,as a matter of convenience or for compliance with a local ordinance.

\Vhat I wish to particularly emphasize in connection with my presentinvention, is its extreme simplicity, cheapness and convenience, itstaking the strain of the wires or cable from the conduit-pipe and itsadaptation to the locality and requirements of its use by arying thelength of one or the other or both of its arms without any other changein the fixture. The bracket may be initially made with arms of the rightlength or with arms ot maximum length, thus providing for cutting themdo W11 to the length required by any given installation.

I claim:

In a conduit-cap for electric installation, the combination with aone-piece bracket consisting of a flat strip of Wrought metal benttransversely to form a vertical suspensioi'i-arin and a horizontalearrying'arm, the former being perforated for being secured to astationary support, and the latter being perforated and threaded for theapplication of the bracket to the threaded end 01 a conduit-pipe; ofWire-insulating-andgripping means mounted upon the upper face of theouter end of the said carrying-arm, and a fol-Wardly-opening hoodadapted in shape and size to protect the said means, to cover the openupper end of the said pipe, and also to clear the suspension-arm of thebracket, whereby the total strain or the service-Wires is imposed uponthe bracket and removed from the conduitqvipe.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses. V
